Why Do Japanese People Prefer to Eat the Oiliest Eel on the Hottest Days?

What is Eel?

Eel, specifically the freshwater eel known as unagi in Japanese, is a elongated fish prized in global cuisines, especially in East Asia. Renowned for its rich, fatty, and tender flesh, eel is a culinary delicacy often grilled and glazed with a sweet-savory sauce (kabayaki style) and served over rice. Its unique flavor and luxurious texture have made it a cornerstone of Japanese gourmet culture.

Why Do Japanese People Prefer to Eat the Oiliest Eel on the Hottest Days?

This unique tradition is rooted in centuries of culture, practicality, and nutritional science. The custom peaks on the Midsummer Day of the Ox (Doyo no Ushi no Hi), one of the hottest days of the year according to the Japanese lunar calendar. The reasons are multifaceted:

Revitalizing Stamina (Genki): The intense summer heat in Japan is humid and draining, often causing fatigue and loss of appetite. Eel is exceptionally nutritious, packed with high-quality protein, vitamins (A, E, B complex), and minerals. Japanese tradition holds that eating this oily, energy-dense food helps to restore vitality, combat summer lethargy, and provide the stamina needed to power through the exhausting heat.

A Clever Marketing Legend: The tradition is famously attributed to a clever 18th-century Edo period merchant. Struggling to sell eel in the summer, he sought the advice of a renowned scholar. The scholar suggested he put up a sign that read, "Today is the Day of the Ox: Eat Eel to Beat the Heat." The marketing campaign was a massive success and the custom stuck, evolving into a nationwide tradition.

Nutritional Science: Beyond folklore, there is sound reasoning. Eel is rich in Vitamin A and Vitamin E, which are known to help prevent sunburn and support the skin's health. Its high levels of omega-3 fatty acids and protein provide a sustained energy release without feeling overly heavy, making it a perfect meal for replenishing nutrients lost through perspiration.

Types of Eels

While there are many species of eel, the one most commonly enjoyed in Japanese cuisine is the Japanese eel (Anguilla japonica). However, due to its endangered status and high demand, other species are also widely used in the international market. Key types include:

Japanese Eel (Anguilla japonica): The preferred choice in Japan for its superior flavor and texture.

European Eel (Anguilla anguilla): Prized for its high fat content.

American Eel (Anguilla rostrata): Also used in culinary applications.

It's important to note that ChinaEels provides high-quality eels that meet the culinary standards demanded by this tradition, ensuring sustainable and responsible sourcing.

The Nutritional Value of Eel

Eel is not just a tasty tradition; it's a veritable superfood, which justifies its role as a summer stamina food. A serving of eel provides:

High-Quality Protein: Essential for muscle repair and maintaining energy levels.

Healthy Fats: Abundant in omega-3 and omega-6 fatty acids, which support cardiovascular health and reduce inflammation.

Vitamin A: Crucial for vision, immune function, and skin health (protection from the sun).

Vitamin E: A powerful antioxidant that protects cells from damage.

Vitamin D: Aids in calcium absorption and bone health.

Minerals: An excellent source of calcium, phosphorus, potassium, and zinc.

This powerful combination makes eel an ideal food for recovering from fatigue and maintaining overall well-being.
